 +Rapid Oscillations in the Solar Atmosphere imaging system, mounted on the Dunn Solar Telescope (DST) at the National Solar Observatory,​ New Mexico, USA (Jess et al. 2010). The instrument is capable of observing simultaneously in 7 passbands at up to 30 frames per second, providing ​ a resolution up to 0.15 arcsec (100 km on the Sun) over a 60 arcsec x 60 arcsec field of view. Combined with a set of tunable and stand-alone filters, ROSA can cover several lines and continua, including Ca II-K and Ha, the Balmer continuum at 3500 Å , the blue continuum at 4170 Å, and the photospheric G-band at 4305.5 Å. ROSA can also be used with a Zeiss universal birefringent filter (UBF) that can be tuned anywhere between 5,000 and 7,000 Å.
